the normal wiring harness for most hondas is the same, so the pigtails will work, but the keyless doesnt work. i had to fix one on a customers car one time, and i found that out, installed the correct install kit (65 bucks i think) and relocated the factory radio and it worked fine.
but, that was one car....i dont know details on yours.
you dont need any install kit. you just need a reverse harness.
dissasemble the factory radio enough to stufff behind the dash. get the reverse harness that plugs into the factory radio and just give it 12v (yellow) ign (red) and ground (black). that is all.
